practical and which may be'operated at a minimum expense. q

Another object of the invention is to provide a pumping system in which there are no movable parts, essential to the operation of the system,below the level of the liquid.

A further object of the invention is to provide a pumping system which may be easily assembled and which will not become clogged by sand. 7

With these and other obj ts in iew, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination andarrangement of parts as will be hereinafter fully described and illustrated. I

Referring to the drawings, Figure 1 1s a longitudinal, sectional view through the injector unit or foot piece of my pumping system. Fig. 2"is a detailed, longitudinal, sectional view through the collar or nozzle forming element of the system. Fig. 3 is a with a foot piece or injecting unit generally designated 3.

A feed pipe or tube 4:, is arranged concentrically around the discharge pipe 2 and isconnected-by a threaded collar 5, to a cylindrical casing or barrel seat 6, formed with an inverted conical bore or passage 7, having a ground wall. mpple 9 to the lower end of the casing 6.

Within the casing 6, is positioned a barrel 10, .of an inverted frusto-conical formation havink its outer surface ground so as to form an air tight joint within the casing.

A head 11, is threaded into the upper end of the barrel and is formed with a conical interior 12, which communicates at its upper end with a, constricted passage 13, formed through the throat 14.

g The upper portion of the head 11- is conical as shown, and is encircled by a collar or nozzle-forming element 15, having a circular peripheral flange 16, at its upper end which is threaded into engagement with the lower end of the discharge pipe 2. This collar has a central conical shaped opening, the wall A collar 8, connects a of which is spaced a slight distance from the head 11, assist in supporting the dis .charge pipe 2 and they space the collar 15 from the head 11 so as to form a continuous passage from the feed pipe to the discharge pipe. Set. screws or pins 20, connect the collar 15 and the barrel head 11.

The barrel 10 has a port 21, formed in its lower end, said port being enlarged adj acent its upper end to receive a removable valve seat 22, having a central circumferential flange 23, which is engaged by the lower edge of a valve cage 24, which cage is threaded into the bottom ofgthe barrel. A ball 25 operates within the cage to open and close the passage 21, leading into the interior of the barrel.

In operation gas is forced downwardly through the feed pipe 4 under pressure and as it flows through the restricted passage 26 into the discharge pipe 2, creates a suction upwardly which draws liquid through the nipple 9, port 21 and head 11 into the discharge pipe and then to the surface.

The discharge pipe 2 is of greater inside diameter than the outside diameter ofthe plpes. r v

A plug 41 closesthe lower end of the barportion of the liquidcolumn and exert substantially direct upward pressure against said liquid. For some reason or reasons which I am unable to fully explain, the fluid pump with this device issues from the well in a steady unbroken stream and the gases and liquid do not discharge alternately in separate puffs such as occur with the use of prior devices.

Should the ball valve 25 or seat thereof become worn the entire barrel and discharge pipe 2 may be withdrawn from the well without disturbing the feed pipe or other portions of the system and this feature I consider to be of primary importance from a practical standpoint.

On Sheet 2 I have shown a slightly modified form of my pumping system, which, as is evident, is somewhat simpler in construction than the preferred form.

In Fig. l the barrel 27 is connected directly to the feed pipe 28 by a threadedcollar 29 and to the nipple 30 by a threaded collar 31. This barrel has a cylindrical chamber 32 at its lower end and a conical chamber 33 at its upper end communicating with a restricted passage 34. The body or main portion of the barrel is cylindrical whereas the upper end 3 5, is reduced to a conical shape. A nozzle forming member or collar 36 encircles in spaced relation, the conical portion 35, and is provided with a flange 3!, which is threadingly. engaged with the discharge pipe 38. The lower end of the member 36 rests against the u wardly facing shoulder 39 of the barrel 2 and is notched-as indicated at 40 to establish communication between the feed and discharge rel 32, and is formed with a port or passage 42 surrounded at itsupper end byan exdrawn from the well without removing also M a straight throat portion of less diameter' than the diameter of the barrel below the throat, means to discharge gases upward around said throat, and a discharge pipe of greater inside diameter than the outside diameter of the throat surrounding said throat so as to form an annular space between the throat and discharge pipe.

2. In a pumping system, a barrel having a straight throat portion of less diameter than the diameter of the barrel below the throat, a collar surrounding and spaced apart from the barrel to form a restricted passage, means to dischargegases upward through said restricted passage, and a discharge pipe of greater inside diameter than n the outside diameter of the throat surrounding said throat so as to form an annular space between the throat and discharge pipe,

'said annular space being of greater cross ternally threaded flange 43 to which a valve 55 cage 44 is connected. A valve seat 45 is housed within the cage and supports a ball valve 46. The valves 25 and 46 check any return flow of oil through passages 21 and 42 respectively and also prevent any gas flowing through these passages, should a back pressure accumulate. I

Although the construction of the modified form of my invention is simpler than that of the preferred form it cannot be so readily repaired because the barrel cannot be withsectionalarea than the cross sectional area of said restricted passage.

3. In a pumping system, a barrel having a straight throat portion of less diameter than the diameter of the barrel below the throat and provided with an upwardly facing shoulder, a collar surrounding and spaced apart from the barrel to form a restrictedpassage and provided at its lower end with notches and having said lower end seated on said shoulder, a feed pipe discharging on to the shouldered portion, and a discharge pipe fastened' to the upper end of' the collar and surrounding said throat, said discharge pipe being of greater inside diameter than the outside diameter of the throat so as to form an annular space between the throat and discharge pipe and said annular space being of greater cross sectional area than the cross sectional area of said restricted pa'xage.

4. In a pumping system, a barrel having a straight throat portion of less diameter than the diameter of the barrel below the throat and provided with an upwardly facing shoulder, a collar surrounding and spaced apart from the barrel to form a. restricted passage and provided at its lower end with notches and having .said lower end freely seated on said shoulder so as to be movable relative to the barrel, a feed pipe discharging on to the shouldered portion, and a dischargepipe fastened to the upper endof the collar and surrounding 'said throat, said discharge pipe. being of greater inside In testimony whereof, I have hereunto set diameter than the outside diameter of the my hand at Los Angeles, California, this throat so as to form an annular space be- 26th day of August 1914.
